This article reviews roles of imaging examinations in the management of community-acquired pneumonia(CAP), imaging diagnosis of specific CAP and discrimination between CAP and noninfectious diseases. Chest radiography is usually enough to confirm the diagnosis of CAP, whereas computed tomography is required to suggest specific pathogens and to discriminate from noninfectious diseases. Mycoplasma pneumoniae pneumonia, tuberculosis, Pneumocystis jirovecii pneumonia and some cases of viral pneumonia sometimes show specific imaging findings. Peribronchial nodules, especially tree-in-bud appearance, are fairly specific for infection. Evidences of organization, such as concavity of the opacities, traction bronchiectasis, visualization of air bronchograms over the entire length of the bronchi, or mild parenchymal distortion are suggestive of organizing pneumonia. We will introduce tips to effectively make use of imaging examinations in the management of CAP.

AIM： To darify bhe efficacy and safety of bhree-dimensional conformal radiotherapy （3-D CRT） for bhis disease and to specify patient subgroups suitable for this treatment. METHODS： Fifty-two patients with HCC received PVItargeted radiation therapy from .January 1995 through December 2003. Portal venous invasion （PVI） was found in the second or lower order branches of the portal vein in 6 patients, in the first branch in 24 patients and in the main trunk in 22 patients. Child classifications of liver function before radiation therapy were A, B, and C for 19, 24 and 2 patients, respectively. All patients received three-dimensional conformal radiotherapy with a total dose ranging from 39 to 60 Gy （57.0 Gy in average）. RESULTS： Overall survival rates at 1, 2, 3, 4, and 5 years were 45.1%, 25.3%, 15.2%, 10.1%, and 5.1%, respectively. Univariate analysis revealed that Child status, the number of tumor foci, tumor type, transcatheter arterial embolization （TAE） after radiation therapy were statistically significant prognostic factors. Multivariate analysis showed that the number of tumor foci and TAE after radiation therapy were statistically significant. CONCLUSION： The results of this study strongly suggest the efficacy of 3-D CRT as treatment for PVI in HCC. 3-D CRT is recommended in combination with postradiation TAE for PVI of HCC with 5 tumor foci or less in the liver and with Child A liver function.

One of the main purposes for which people use Twitter is to share emotions with others. Users can easily post a message as a short text when they experience emotions such as pleasure or sadness. Such tweet serves to acquire empathy from followers, and can possibly influence others＇ emotions. In this study, we analyze the influence of emotional behaviors to user relationships based on Twitter data using two dictionaries of emotional words. Emotion scores are calculated via keyword matching. Moreover, we design three experiments with different settings： calculate the average emotion score of a user with random sampling, calculate the average emotion score using all emotional tweets, and calculate the average emotion score using emotional tweets, excluding users of few emotional tweets. We evaluate the influence of emotional behaviors to user relationships through the Brunner-Munzel test. The result shows that a positive user is more active than a negative user in constructing user relationships in a specific condition.

Tuberculosis(TB) is still a major health problem worldwide. We present a rare case of an immunocompetent patient with perianal TB. A 38-year-old man visited a clinic with pain, swelling, and redness in the perineum. He had been persistently coughing for the past 6 mo. The abscess had formed a fistula to the perianal region, indicating perianal abscess. Mycobacterium tuberculosis was found in sputum and perianal abscess. Surgical drainage was performed, and oral anti-tuberculous drugs were administered for 6 mo. The patient's clinical course was favorable. On review of the literature on 58 cases of perianal TB, we found that the duration of persistent perianal lesion was much longer in patients without active pulmonary TB(APTB) than in those with APTB(66.4 mo vs 8.3 mo; confidence interval, 0.0760-0.9620, P = 0.0380). Thus, in cases of non-healing or recurrent perianal lesions, TB should be considered.

Recent epidemiological studies showed that daily coffee consumption is associated with a lower risk for several neurological disorders such as Alzheimer’s disease and Parkinson’s disease;however, the molecular mechanisms responsible for the protective effect of coffee against neurological disorders have not been elucidated. As brain-derived neurotrophic factor (BDNF) promotes neuronal survival and protects against neuronal damage, we investigated the effects of coffee on BDNF signaling using human neuroblastoma SH-SY5Y cells. We found that brewed coffee exerted an inhibitory effect on the autophosphorylation of tropomyosin receptor kinase B (TrkB), a BDNF receptor. Additionally, coffee reduced the phosphorylation of Akt in BDNF-treated SH-SY5Y cells. Treatment with coffee did not affect the TrkB receptor on the cell surface. The major constituents of coffee, such as caffeine, caffeic acid, chlorogenic acid, and trigonelline had no effect on TrkB phosphorylation induced by BDNF. In addition, coffee reduced the BDNF-induced increase in BDNF gene expression and the neurite outgrowth promoted by BDNF. Our data suggest that the protective effect of coffee reported in epidemiological studies against neurological disorders may not be associated with BDNF signaling through TrkB.

Back ground: There are no published clinical data in hemodialysis (HD) patients with mineral bone disorder (CKD-MBD) regarding the effect of sevelamer hydrochloride on the absorption of the oral calcitriol. Objectives: The aim of the present study was to determine the association of the sevelamer hydrochloride and serum 1-25(OH)2D concentration during oral calcitriol therapy. Methods: This was a before-and-after study in HD patients. Forty-six patients co-administered with phosphate-binder and calcitriol for CKD-MBD therapy took lanthanum carbonate (LC) and sevelamer hydrochloride (SH) for 4 weeks, respectively with calcitriol. The serum 1-25(OH)2D concentration was assessed after each period. Results: Serum 1-25(OH)2D concentration was significantly reduced with co-administration of SH compared to LH (mean, calcitriol with LC→SH: 19.9 pg/ml → 14.2 pg/ml, p 2D concentrations after oral calcitriol administration compared to LH in HD patients. When we use SH as a phosphate binder with calcitriol for HD patients with CKD-MBD, we should consider the inhibitory effect of SH on oral calcitriol absorption.

A novel air-cleaner with a coil-shape photocatalysis-plasma synergistic reactor was developed. The air-cleaner showed 95% ± 1% reduction of a TVOCs concentration in tobacco smoke at “single-pass” condition. Air-purification activity of the air-cleaner was stably-maintained after the treatment of 12,000 cigarettes of tobacco smoke.
